Project Description
Project focus: paint line process in the sheet metal section of the facility
Concerns Quality of paint job Environmental emissions Employee exposure to chemicals/fumes
![Page 4: Powder Coat Pp](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bc80224a79599d738b4582/html5/thumbnails/4.jpg)
Current Sheet Metal Paint Process
Parts are prepared (manually sanded and wiped down) to help paint adhere to surface better
Parts are hung on a conveyor system Parts go into paint booth via conveyor
and are painted Go into curing oven to bake and dry

Problem ID: Current Paint Process Open-Ended Wet Spray Paint Booth System was grandfathered in; old equipment,
ventilation, etc. Leads to inadequate paint jobs and poor air purity
Many parts are “defective”- need to be re-prepped and re-painted
Employees handle and are exposed to amounts of solvents, paint thinners, etc. which are hazardous
Majority of Haz. Waste of facility produced here

Problem ID: Current Process (Production)
Shipping Some parts need to be powder coated, so
they are shipped out; leads to issues with quality and hinders productivity
Lost time on labor-handling, inspecting, and inventory on shipped parts
WIP Materials

Solution
Implement a new powder coating paint line Will greatly reduce
environmental safety concerns
Will increase quality of product, productivity, and lead to more business
![Page 11: Powder Coat Pp](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bc80224a79599d738b4582/html5/thumbnails/11.jpg)
Solution:Proposed New Powder Paint Line
Preparation-5-Stage Wash system Parts treated with chemicals to enhance
ability of paint to adhere to surface Powder Paint Booth Bake Oven
Parts moved via conveyor system
![Page 12: Powder Coat Pp](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bc80224a79599d738b4582/html5/thumbnails/12.jpg)
What is Powder Coating?
Applying dry paint to a surface Paint powder is
applied to the surface and put in an oven to bake
Results in a durable, even-coated finish
Preparation and baking are key to a good finish
![Page 13: Powder Coat Pp](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bc80224a79599d738b4582/html5/thumbnails/13.jpg)
Advantages of Powder Coating Releases little to no VOCs and HAPs into
environment (solvents, thinners) Reduces employee exposure to these harmful
chemicals Reduces burden of EPA compliance for
facilities Overspray of powder is easily recyclable Better paint quality
No drips, runs, or other imperfections Reduces defected parts; less preparation time
Durable, Non-Corrosive Finish

Problem Solution: Air Emission Permit
Obtain a new air emission permit
Everbrite is currently under a Part 70 permit Requires extensive
reporting and not many advantages
Everbrite should obtain a Registration Operating Permit (ROP)
![Page 15: Powder Coat Pp](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bc80224a79599d738b4582/html5/thumbnails/15.jpg)
ROP Permit
Allows facilities to change processes/do construction without obtaining other expensive construction permits Saves time and money Must stay within limits of ROP during construction
Less extensive and less frequent reporting and recordkeeping than Part 70
Easy application process; short waiting time Don’t need to hire consultant to handle permit
Costs less than Part 70 Doesn’t Expire
![Page 16: Powder Coat Pp](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bc80224a79599d738b4582/html5/thumbnails/16.jpg)
Emission Citations
Under Part 70- Automatically considered a High Priority Violation (HPV) Forwarded to the EPA Possibly referred to the Department of Justice
![Page 17: Powder Coat Pp](https://reader033.fdocuments.in/reader033/viewer/2022061220/54bc80224a79599d738b4582/html5/thumbnails/17.jpg)
Emission Citations
Under ROP- not automatically HPV Facility is sent a Letter of Notification
(LON) Facility replies on how to make sure the
violation doesn’t re-occur Follow up visit
*Depends on violation for both Part 70 and ROP ROP most likely less serious than Part 70

Expected Results/Benefits
VOC/HAP emissions will decrease Less employee exposure
Less Hazardous waste produced Less recording/reporting to EPA
Not as much administrative burden to keep records
